my new AR headers came with 02 extensions. i guess the idea is to use the stock oxygen sensors and these extensions will plug into the factory plug and the other side will plug into the 02 plug. are these ok in terms of quality and everything? i just didn't know if it would be better off for me to just buy some corvette bosch sensors or use these?

They're fine. It's probably a good idea to upgrade to the vette ones though if you got a few extra bucks laying around. I've already burnt out 2 of the stockers.

i don't have a problem with that. i think the bosch plugs are just as cheap if not cheaper than the stock ones. i have been told the stock ones are a bit more sensitive. that is an ongoing battle (stock vs. bosch) when it comes to oxygen sensors.

by the way, are the front and rear 02 sensors the same? i was looking them up on gmpartsdirect and it only says left and right. it doesn't say anything about front and rear.

do yourself a favor and buy the 13111 bosch o2's

They're interchangeable.

here is a thread showing the differences between left and right ones. i just didn't know why there were differences.

Mine look exactly the same

do you mean the same on both sides or the same as the ones in the picture?

Mine look the same all around. They just have different length wires on them for the different sensors, that's all. They all have the slotted heads on them.
